Measure for Measure

Thyself and thy belongings
Are not thine own so proper, as to waste
Thyself upon thy virtues, them on thee.
Heaven doth with us as we with torches do,
Not light them for themselves; for if our virtues
Did not go forth of us, ’t were all alike
As if we had them not. Spirits are not finely touch’d,
But to fine issues, nor Nature never lends
The smallest scruple of her excellence,
But, like a thrifty goddess, she determines
Herself the glory of a creditor,
Both thanks and use.
